WTS: HK Rollers, 18-options from $2 (pics)

1 post in this topic

Rollers are one of the most important parts for your HK roller style weapons. Rollers by design are amazingly hard yet not brittle. German HK rollers have a Rockwell hardness of 60-64 (depending on era). HK contract rollers also have a Rockwell hardness of 60-64 as they are made from the same high-quality HK spec material. All of the U.S. made rollers have a Rockwell hardness in the 40's. That is WAY too soft. We stocked some of the U.S. made rollers when they were the only option available. Today however there are better choices. The quality of our German HK or HK Contract rollers cannot be matched.

If choosing between U.S. made or HK spec. Do not settle for less than HK or HK contract production.
